HANGER EoR AXMINST'ER-LOOM TUBEy FRAMES.

Application filed December 3, 1926. Serial No. 152,480.

This invention relatestoimprovements in tube frames for Axminster loomsandit is the principal object ofthe invention to provide a rigidsuspension member for the chain F sov constructed as to be readilyremovable without disturbing the bracket or spool bearing.

Amninster looms employ a .pair-of spaced endless chains between whichextend the tube frames upon which are mounted the yarn spools. Each tubeframe is provided at the ends thereof with spool supporting and chainengaging brackets, each bracket having a bearing fory a spool gudgeonand also having a tongue toenter the space between a double linkofthechain. The chains aretrained over guide sprockets and the tube framespass from one side tothe other of a vertical line passing throughthefcenters of 20 the sprockets. This' movement' ofthe tube framesubjects the brackets to constant strain and in order to keep thebrackets tight they are fixed securely to the tube frames.

Vhen rigid chain engaging latches such 25.as shown in patent to Ryon#1,462,560 are used it is found that renewal of latches can beaccomplished only by removing the bracket from the tube frame. After thebrackets have been renewec several times they lack the tight tit whichthey should have to withstand the aforesaid strains. It is accordinglyany important object of my present invention to provide a rigid latchwhich shall be readily removable and renewable without disturbing the'setting of the brackets relatively to the tube frame. l

It is a more particular object of my 1nvention to provide a'springvlocated inside the hollow bar ofthe tubeframe and removable throughaligned openings in the bracket arms and adjacent'wall of the tubeframe.'r

lVith these and other objects which will appear as the descriptionproceedgmy invention relates to the arrangements and commoreparticularly pointed out in the claims. In the accompanying drawings,"wherein a convenient embodiment of my invention is shown-n f* Fig. 1 isa vertical central section through a portion of thetube `frame having myinvention applied thereto, thev spool chain and releasing clutch beingshown in section and V binations of parts lhereinafter set forth, and

Referring to the drawings it will be seen that I have provided a tubeframe 10 having ahollow tubular bar 11 to which are secured a pluralityof yarn tubes 12. Each end ofthe tube frame is provided with a bracket,one of which is indicated in Fig. 1 having a spool bearing member 13provided with a horizontal leg lt extendingrinto the hollow tubular bar11. Said bracket is also provided with a chain engaging member 15 havinga horin zontal leg 16 extending into the bar 11 along the bottomthereof. `Screws 17 may be provided to secure the arms iny place andsaid members may be secured together by having adjacent parts welded toeach other. f Mern ber 15 has a horizontal slot 18 and an off-set tongue19 arranged to pass betweenthe links 20 of the transporting chain;y Aspool is mounted for'rotation on the member 13 and has wound thereon aplurality of threads whichextend through the yarn tubes 12.

. The lower end of memberl may have a projecting lug 21 positioned tolie under the disengaging stud 22 of clutch C, the purpose of the lugbeing to engage the stud 22 and prevent downward movement of the clutchto effect rStopping of the loom as set forth in patent to Striemer#1,546,685. yThe matter thus fardescribed is old and forms'no part of mypresent invention except the Size hook member 32 has al head 83 toengage one ot' the chain elements 20 and said mem ber extends downwardlythrough horizontalslot 18 and vis Jformed atits lower end with ahorizontal `extension 34rwhich passes through vertical slot 30. Saidextension 234 bent to have an upwardly opening notch 35 in the bottom orwhich is located the pin 3l. The inner end of the extension 34 .hasstruck therefrom a tongue 36 which guides the upper end ci compressionspring 3T and the lower end of said spring is guided by a conical point38 toi-med on screw 39. The space between the extension 34 and leg 16 isequal to or slightly greater than the distance between the bottom of thepin 81 and the top et that portion ot extension 34 which projectsinwardly from the pin.

,Under normal operating conditions spring 3?" will tend to hold hookmember outwardly in the position shown in Fig. l with the head 33 lyingover one of the chain elements to support the tube iti-ame. At thetinieof transfer when the tube -frame is to be conveyed from the chainto the fabric, stud 22 et the clutch will engage the vertical portion otthe hook member and move the same so that head 83 will be out otvertical alignment with the adjacent chain element and the walls l0 et'the clutch will be in engagement with the vertical sides ot the memberl5. Alfter the tufts have been incorporated into the fabric the clutch.C will be raised and then moved `longitudinally away from the tubeli'anieto `permit the head 83 to move over a portion of the chain.

Because orn the frequent movement et the hook members they occasionallybecome bent or broken or for other reasons need replacing. lilhenthiscondition arises screw 3S may be withdrawn from the tube frame and thespring` moved downwardly through the bore tor the screw 39. Tofacilitate this operation the diameter oit the spring 37 is preferablyslightly less than the bore of the hole which receives the screw 39. 'With the spring 3T removed the hook member 32 can be moved downwardly sothat the upper portion ot the extension Se may pass under the pin 31.Fig. l indicates the mannerin which the hook may be removed. The newhook can be replaced by an operation the reverse of that described forremoving the old hook. In this way the bracket canV be held securely inplace on the tube frame whilethe portion most subject to wear isremovedl aud replaced without disturbing the spool.

From theioregoing it will be seen that I have provided a tube frame witha. bracket which may be readily renewed without ldisturbing the settingof the bracket relatively to the tube traine. I do not claim the rigidlatch per se as such a device is shown in British patent to 'Ionikinsonet al. #21,644

nea-1190` of 1906, and I do not claim the ideaof the latch beingconnected to the bracket in-substantial alignment with the axis of theyarn tubular bearing member, as this construction is old, as may be seenin .patent to (frceiihalgh #26a-,281, but I believe I am the iirst toprovide a rigid cha-in engaging hook member having an extension inside ahollow tubular bar and having contact with the frame in sucha way as topermit ready renewal of a damaged hook member Iwithiout disturbing' orin any way interfering with the spool bearing bracket.

Having thusA described my invention it will be apparent. that changesand` modifications kmay be made therein by those skilled in the artwithout,departing from the spirit and scope ot' the invention, and I donot wish to be limited to the details herein disclosed but what I claimis:

l. In a tube trame for Axininster looms, tubular bar, a. spool bearingbracket secured thereto, and a. rigid hook member pivotally mounted onthe bar and readily ree movable from the tribe frame while the bracketis secured to the bar and a spring for said hook member adapted to beinserted through an opening in a side wall of said bar and engaging saidhook member when thus inserted and effective to tension said hook memberand to prevent accidental displacement thereof.

2. In a tube frame forAXininster looms, a tubular bar, a spool bearingbracket secured thereto7 and a rigid hook member extending into the barand pivotally mounted on the bar and readily removable from the tubeframe while the bracket is secured to the bar. Y

3. In a tube frame for Axminster looms, a tubular bar, a spool bearingmember secured thereto, a rigid hook member pivotally mounted withrespect to the tubular bar and extending through a portion of thebracket, and connections between the hook member and bar, whereby saidhook member may be readily removable while the bracket remains attachedto the tubular bar.

ll. VIn a tube frame for Axminster looms, a tubular bar, a spool bearingand chain engaging bracket secured thereto, a rigid hook member havingpivotal connection with the tubular bar and extending through a port-ionof, the bracket and being readily removable while the bracket is securedto the tubular member, and resilientmeans tend-` ing normally to holdthe hook member in outward position. i

5. In a tube framefor Axminster looms having transporting chains, atubular member, a spool bearing and chain engaging bracket securedthereto, said bracket having an opening therethrough, a rigid hookinein-l ber pivotally mounted on the tubular member Vand, extendingthrough said bracket opening, a resilient member engaging that portionof the hook memberl located within the tubular member, and readilyremovable means forholding the resilient member in position to cause thesame normally to move the hook member outwardly,

6. In a tube frame for Axminster looms having transporting chains, atubular bar, a spool bearing and chain engaging bracket secured thereto,said bracket having an opening therethrough, a yrigid chain lengaginghook extending through said bracket opening and into the tubular bar,means defining a pivotal connection between the 'hook and tube fram-eindependent of the bracket, and resilient means tending to hold the hookoutwardly, the pivotal connection between the hook and tubular bar beingspaced vertically over adjacent parts whereby the hook may be readilyremoved while the bracket is secured to the tubular bar.

7. In a tube frame for Axminster looms having a transporting chain, atubular bar, a spool supporting and chain engaging bracket securedthereto and having an opening therein, arigid hook member extendingthrough the opening and into the tubular bar, means extending across theinterior of the tubular bar to engage the hook and define therewith apivotal connection 4for said hook, said means being spacedverticallyfrom adjacent 'portions of the bracket, whereby the hookmay beremoved while the bracket is in iXed position relatively to the y inginto and secured to the hollow member,

said bracket having an opening therethrough, a rigid hook member havinga portion vlying outside the tubular member and having a portionextending through said bracket opening into the hollow member, 'if

said hook member having an upwardly opening notch, a device secured tothe hollow member and normally located in the bottom of the notch toafford a pivotal connection between the member and thehook, andresilienty means tending to hold the khook against the device and inoutward position relatively to the bracket, the depth of the notch beingsuch that the hook can be removed by a combined downward and lengthwisemotion relatively to the tubular bar without removing the bracket fromthe member.

In testimony whereof I have hereuntoafkfixed my signature.
